Miele Dryer: compressor noise

Professional Repair Guide

What is this symptom?

If your Miele dryer is producing a buzzing or humming noise from the compressor or heat pump area during operation, it may be normal. This sound is common in heat-pump dryers and often indicates that the appliance is functioning correctly. However, it’s important to ensure that clothing is drying properly and that there are no unusual mechanical noises present.
